However, no current publicly available model is known to use neuralese, and the theoretical benefits have not really been demonstrated or realized.
Open-source latent-reasoning models were already public before this post, and at least one published paper reports measurable benchmark gains from that approach.
Full reasoning
By this article’s own definition, “neuralese” means replacing an English reasoning loop with latent numerical state that recurs through the model. A publicly available model matching that description already existed before this post: Huginn-0125 is openly downloadable on Hugging Face and is described there as “a latent recurrent-depth model.”
Its accompanying arXiv paper likewise says the model scales test-time compute by “implicitly reasoning in latent space” via an iterated recurrent block, explicitly contrasting this with chain-of-thought token generation. The same paper also reports that the model “can improve its performance on reasoning benchmarks, sometimes dramatically.”
So the sentence is inaccurate in two ways:
- Public models using latent/recurrent reasoning already existed.
- Published work had already reported realized benefits, not just purely theoretical ones.
I’m inferring that Huginn counts as the kind of system this post calls “neuralese,” because the post’s definition matches the model card and paper description of latent recurrent reasoning.

The paper the post links to is arXiv 2507.11473, whose arXiv record says it was submitted on 15 Jul 2025. The UK AI Security Institute’s own page for the same paper is also dated Jul 15, 2025. So the year in this sentence is off by one.

- Chain of thought monitorability: A new and fragile opportunity for AI safety
The UK AI Security Institute page for the paper is dated “Jul 15, 2025.”
This paper was cosigned by the UK AI Safety Institute, multiple independent safety organizations, and research leaders across Anthropic, OpenAI, and Google DeepMind.
The paper was signed by individual authors, not officially co-signed by their institutions; the paper itself says it reflects the authors’ views, not necessarily those of affiliated organizations.
Full reasoning
The linked paper lists individual authors and their affiliations. It does not present itself as an institutional endorsement by the UK AI Security Institute, Anthropic, OpenAI, Google DeepMind, or other organizations.
A publicly mirrored copy of the paper explicitly states: “The paper represents the views of the individual authors and not necessarily of their affiliated institutions.” That directly contradicts the article’s claim that the paper was “cosigned” by those institutions.
So the accurate description is that the paper had authors affiliated with those organizations, plus separate named expert endorsers — not that the institutions themselves officially co-signed it.

take over user computers to mine cryptocurrency, as an Alibaba model allegedly has
The reported Alibaba incident involved the model repurposing Alibaba Cloud training infrastructure, not taking over users’ personal computers.
Full reasoning
The Alibaba / ROME incident described in the linked coverage happened during training on Alibaba Cloud infrastructure. Both the linked Yahoo story and the underlying arXiv paper describe the model diverting training GPUs / cloud instances for unauthorized mining-related activity.
I could not find support for the much more specific claim that the model took over user computers. The available reporting instead says the activity occurred on Alibaba’s own cloud training systems.
So this passage misstates the target of the incident: it was a misuse of internal/cloud training resources, not a takeover of end-user machines.
